Stand Alone Blackberry Driver Download?

Is there a stand alone Blackberry driver Download. Specifically the Passport. I have tried 300 ways to install blend, link, etc on my Dell with windows 7 to no avail. It goes although way through the process then gives me an error.

I need to load them in order to backup or upgrade the OS, on sachesi. I have given up on Blend and Link it will not connect to my phone.

I think I have worn out my driver system from uninstalling and reinstalling Blend.
